It was all in the RNS fella, devil is in the detail...
With regards to the test performance, an evaluation of pilot batch products showed a test sensitivity of 100% (95% confidence interval 92.6% to 100%) and specificity of 98.4% (95% confidence interval 95.4% to 99.7%). These figures have been calculated following analysis of a total of 186 samples taken from individuals pre-September 2019 (negatives) and 48 patients who had symptoms of COVID19, a positive PCR result for the virus or both. Results are from analyses performed at the University of Ulster and Abingdon Health laboratories and follow an earlier analysis at Imperial College, London of 188 positive samples using pre-design freeze devices which showed a 95.7% sensitivity.
If the population is assumed to have a 10% incidence of COVID19, the AbC-19 pilot batch test shows a 98.6% accuracy
